PROCESS OF OBTAINING FERTILIZER.

Application filed May 28, 1913.

To all whom it may concern:

Be it known that I, WVILHELM I-I. HEINE, a citizen of the United States,residing at Honolulu, in the county of Honolulu and Territory of Hawaii,have invented new and useful Improvements in Processes of ObtainingFertilizer, of which the following is a specification.

The object of the present invention is to provide a cheap and efficientprocess for obtaining fertilizer from the gases escaping from anordinary gas engine.

In carrying out my process the products of combustion from an ordinarygas engine are first run through a suitable cooling device, after whichthey are passed through a chamber in which they are treated, with ashower of lime water.

The accompanying drawing shows a diagrammatic side elevation, partly insection, of the apparatus used in carrying out my process.

In said drawing, 1 represents an ordinary gas engine, which may be ofany of the usual types now in use. The gaseous products of combustionare passed by means of a pipe 2, through a worm 3, located within achamber 4, which chamber is provided at the bottom with a water inlet 5,controlled by a suitable valve as illustrated.

The gases after having been passed through this cooler are conveyed bymeans of a pipe 6, to an absorption chamber 7, in which they are treatedwith a shower of lime water, which liquid is caused to pass downwardlythrough the ascending gases a number of'times, for example, by means ofthe pump 8 and pipes 9 and 10. The liquid leaving the pipe 9 isdistributed by means of the perforated plate 11, in such a manner as toproduce a shower of lime water, which will come very thoroughly intocontact with the gases passing upwardly through the absorption chamber.

The liquid after having been used for some time in connection with thegas is drawn off from the bottom of the absorber and may be treated byeither of the two following steps.

The liquid togetherwith whatever solid matter may be mixed with it, isevaporated to dryness to form a fertilizer; or the liquid may be addedto the water used in irrigating land.

While I am unable to give a full and complete statement of the chemistryinvolved in this process, it has been found that the fertilizer producedin this manner contains, among other things some calcium nitrate whichis a very eflicient fertilizer,

since it contains both calcium and nitrogen m a readily solublecondition.

The fertilizer also contains a considerable to any gas engine and willproduce this valuable by-product at substantially no cost, consequentlythe process is extremely economical.

In order to obtain a very thorough mixture of the gas with the limewater, the pipe 6 may enter the absorber 7 tangentially as illustratedat 12.

I call attention to the fact that the gas engine is run in my process,in the usual way, and it is not at all necessary to introduce water orother cooling agents, into the interior of the cylinder, at any stage ofthe operation. This is a surprising discovery in view of U. S. Patent toHausser, 961,350, June 14, 1910.

What I claim is:

A process of producing a fertilizer from the gaseous products ofcombustion of agas engine which comprises cooling these products, thentreating the same with lime water in a suitable. absorber, said limewater being circulated in contact with said gas until a desired amountof fertilizing substances have been absorbed thereby.

In testimony whereof I aflix my signature in presence of two witnesses.
